Epidemiological situation analysis of cutaneous leishmaniasis in Batna (northeast): An important focus in Algeria.

Abstract

Cutaneous leishmaniasis (CL) is a parasitic infection which poses a real public health problem in various countries, including Algeria. We aimed in this study to investigate the current epidemiological situation of CL in the wilaya of Batna (northeastern Algeria) during 2010-2020 and to discuss some control measures used to combat the disease in the most endemic foci. Data on CL cases and control measures were obtained from the "Direction de la Santé et de la Population (DSP) of Batna" and the "Etablissement Public de la Santé de Proximité (EPSP) of Barika". Data were analyzed and mapped using Microsoft Office Excel 2007, SPSS.21, and ArcGIS 10.3. A total of 9259 cases were notified, with a peak incidence of 1924 cases in 2010. The annual evolution of the disease showed decreasing and increasing trends during the study period. Cases were detected year-round, with a peak notification in November (1957 cases) and January (1663 cases). CL affects both genders and all age groups with predominance for males (58.6%) and infants less than 9 years old (54.4%). Most cases have occurred in western areas of the wilaya especially in the commune of Barika with 2979 cases (32.17%), followed by Abdelkader Azil (13.37%), Bitam (12.32%), Djezzar (8.67%), Ouled Ammar (7.07%), and Amdoukal (4.36%) communes. Spatiotemporal analysis showed that the highest frequencies of CL were exclusively reported in the western regions. There was no evidence of a possible relationship between Deltamethrin house spraying and leishmaniasis incidence. This study revealed that CL is highly endemic in the western areas of Batna, especially in Barika, with children less than 9 years old as the most age group at risk. The development of control measures and the selection of appropriate strategies are necessary to prevent, control, and eradicate the disease.
